With a 3\/16-inch drill diameter, a 4-inch flute length, and a 6-inch overall length, this bit is sized for anchor holes, fastener penetrations, and conduit routing through concrete, block, and brick. The SDS-Plus shank provides positive engagement in any SDS-Plus compatible rotary hammer, eliminating slippage under load. The carbide cutting tip resists wear and thermal breakdown in abrasive masonry materials. This is a trade-use bit suited for electricians, plumbers, and HVAC technicians who regularly drill concrete or block substrates during installation work.\u003c\/p\u003e\u003cp\u003eThis bit is designed for use in light to medium masonry drilling tasks common in residential and commercial construction and mechanical rough-in work. Typical applications include setting concrete anchors for equipment hangers, drilling penetrations for pipe and conduit sleeves, and creating chase holes in CMU block walls. The 3\/16-inch diameter is a common size for tapcon-style anchors and small-bore penetrations. This bit ships as a single unit and is available in a 100-piece pack quantity, making it appropriate for contractor restocking or tool crib replenishment.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCarbide cutting tip for extended service life in concrete, brick, and block\u003c\/li\u003e\n\u003cli\u003eSDS-Plus shank for positive chuck engagement and efficient hammer energy transfer\u003c\/li\u003e\n\u003cli\u003e3\/16-inch cutting diameter suits common masonry anchor and penetration applications\u003c\/li\u003e\n\u003cli\u003e4-inch flute length provides efficient debris clearance during rotary hammer operation\u003c\/li\u003e\n\u003cli\u003e6-inch overall length allows reach through standard wall assemblies and block courses\u003c\/li\u003e\n\u003cli\u003eLightweight at 0.05 pounds per bit for reduced fatigue during extended drilling tasks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with any SDS-Plus rotary hammer accepting the standard SDS-Plus shank profile, which is the dominant chuck format across professional-grade rotary hammers in the trade market.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of this bit requires a rotary hammer set to hammer-drill mode; use in a standard drill-only mode is not recommended and may damage the bit or tool. Always wear eye protection and a dust respirator when drilling masonry, as silica-bearing dust is a respiratory hazard subject to OSHA standards. Verify the drilling path is clear of embedded conduit, rebar, or post-tension cables before drilling, using a scanning tool where required. Allow the bit to cool between extended drilling sequences to preserve carbide tip integrity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: SDS-Plus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 13\/32 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrill Bit Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Masonry\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 piece\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MILWAUKEE TOOL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 48-20-7990\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MILWAUKEE","offers":[{"title":"Default Title","offer_id":51702697460018,"sku":"48-20-7990","price":605.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fe22189006246652b20f6c5cd462ee42.jpg?v=1788412827","url":"https:\/\/voomisupply.com\/products\/milwaukee-tool-48-20-7990-sds-plus-carbide-drill-bit","provider":"Voomi Supply","version":"1.0","type":"link"}
